Working Theory

A popular alteration amongst performance enthusiasts is to remove, gut or hollow the catalytic converter or to install an aftermarket header, to free the horsepower of the vehicle. Nowadays, vehicles are fitted with two up to four lambda probes, at least one upstream o2 sensor that controls the fuel management system, and at least one downstream that monitors catalyst converter function. When the aftermarket headers are installed or catalysts are eliminated, the result is a catalyst efficiency ECM code indicating that the cat converter is missing or not functioning properly. The tuned-up engine now produces a larger amount of exhaust gases than allowed. Obviously you do not want to drive your Nissan Gloria with a constant MIL light, in addition your vehicle will not pass emissions in many areas with an illuminated check engine light. The only solution is to install an Nissan Gloria O2 simulator wired up to the aftercat exhaust gas oxygen sensor’s harness in order to simulate a properly functioning oxygen sensor. It provides the ECU with mimic, fluctuating voltage signal and overrides the Electronic Control Unit into thinking the emission is normal. This Nissan Gloria oxygen sensor simulator will allow you to run without catalysts and still keep the CEL off.

When check the engine light is tripped, the engine runs in ECU Safe mode, which is equivalent to restricted power and spoiled fuel mileage. This Heated Nissan Gloria O2 Sensor Simulator eliminates up- and downstream sensors as well, fulfilling the prerequisite of sensor type, thus you can get rid of suffering service light. Magnum Oxygen sensor simulator is available to all vehicles on which the emissions are monitored through a 1 up to 4-wire narrowband zirconia lambda probes working in a 0 up to 1.0 Volt fluctuating voltage range. It also features a standalone adjustable heater simulator circuit. Feel free to contact our engineers prior to purchase if you are unsure about your Nissan Gloria's sensor type. Magnum Oxygen sensor simulator cures all lean mix and other exhaust air fuel sensor related ECM codes caused by heavy exhaust alterations. Dual exhaust with 2 aftercat lambda probes requires 2 O2 sensor simulators. Our digital O2 Sensor Simulator is adjustable, making you enable to adjust the Air/Fuel Ratio within a certain range that is still accepted by the Powertrain Control Module. You can now completely eliminate the zirconia narrowband type oxygen sensor.

Note

upstream exhaust air fuel sensor has to work flawlessly. Slow signal of front exhaust o2 sensor may prevent the oxygen sensor emulator from working. Headers require both up- and downstream O2 sensor emulation. In case of a single oxygen sensor or dual pipe exhaust system fitted with 2 exhaust o2 sensors only, the oxygen sensor simulator wires into these exhaust gas oxygen sensors. Oxygen sensor simulator is a racing part. It is not CARB approved. Please be aware of the bylaws and regulations, O2 sensor eliminator is not street legal in several US states and countries.

Magnum Nissan Gloria Oxygen Sensor Simulator is a must-have upgrade if you are planning to remove, hollow or gut the converter or even if you installed a catalyst converter delete, an aftermarket header, a free flow catback or performance catalytic converter. Are you in the market for the ultimate solution for curing exhaust gas oxygen sensor related service engine soon light on your Nissan Gloria? Then you’ve come to the right place.

How can I figure out my sensor is a zirconia type?

Zirconia type lambda sensors have 1 to 4 wires. 1 to 3 wires indicate a zirconia narrowband o2 sensor definitely. In the case of 4 wires, two of the wires have to be identical for heater, whilst the rest 2 wires have to be different for signal sender and signal ground. Always reference the sensor-side colors of the wires coming out off of sensor head. ECU-side colors may convert through the plugs.

How to find out if it's a narrowband or wideband?

Typically 1 to 4-wire oxygen sensors are narrowband. There are exceptions though. A narrowband oxygen sensor's signal is constantly fluctuating in a range of 0 to 1.0 Volts depending on oxygen content in the exhaust gas. Any oxygen sensor that produces higher voltages, is determined to be a wideband oxygen sensor. Keep in mind, although a 4-wire O2 sensor can be wideband too, in common sense only 5 or 6-wire sensors are called wideband. If your O2 sensor has more than 4-wires, oxygen sensor simulator is not applicable.

Which sensor has to be tricked?

In general: the downstream but upstream has to work flawless in full range. If you intend to buy a simulator hence decatting, header or modified exhaust, the downstream sensor has to be fooled by all means. See position diagram Headers or precat gutting requires upstream simulator as well.

Questions and answers

Can I be positive this chip fixes my CEL issue for good and all?

Yes, Magnum oxygen sensor simulator produces a random fluctuation having assigned with suitable cycle and wave accepted by the ECU. Rest assured, all oxygen sensor related codes will be gone. Upstream sensor if any has to be in good condition though. Please see prerequisites pertaining to sensor type and quantity of simulators.

What if I simply eliminate factory oxygen sensor?

Oxygen sensor removal will not remedy CEL issue. Suitable fluctuating signal is fundamental to be delivered by the ECU. Zero volt signal triggers another trouble code.

Why is it so important to cancel the trouble code?

While check engine light is on, ECU restricts the engine performance and vehicle is running in safe / limp mode. MPG is also affected negatively.

Do I need to buy this heated simulator or I can stick with cheaper EZ CEL Fix?

If you can use the heater of the factory oxygen sensor(s), you may wire up #795 EZ CEL Fix. This heated simulator #661 allows you to remove or eliminate the stock oxygen sensor completely.

What about 'oxygen sensor bungs' 'mini cats' or any other piggybacks are also supposed to sort our FI problems?

The market is teeming with physical gadgets aiming to fix CEL issues. Vast majority of them doesn't take effect on OBDII vehicles made after 1996. They often don't work even on early fuel injected cars. If your vehicle had been manufactured after 1996 or you drive an early model controlled by a sensitive ECU, these gadgets won't help. The definite solution is a circuit conditions realistic signal, as if a working oxygen sensor would be screwed in the factory exhaust.

Can I rally my two harnesses into one simulator?

No, simulators can't be spliced. Get rid of oxygen sensor related CEL issue yet today. Flat catalytic converter gutting or plain-tube decats will spoil low- and mid-end torque hence ruined engine flush due to inadequate exhaust back pressure and higher block temperature thus valves, cylinder head and other engine parts are constantly being exposed to undesired extra heat. True enough, maximum horsepower increases it still pertains to a higher RPM which perishes dynamic kick out acceleration throughout the RPM range, mostly on automatic vehicles, therefore to save money on fuel and enhance low and mid-end torque, highly recommended to install a reliable Decat . Plain decatting is judged unprofessional among serious tuners and enthusiasts. Injected gasoline engines controlled by Electronic Control Unit (ECU) or alias Electronic Control Management (ECM) have oxygen sensor or O2 sensors to measure the amount of oxygen contained in the exhaust gas. These sensors deliver the ECU fluctuating voltage according to the actual oxygen consistence of air fuel mixture. When exhaust system is decatted or heavily modified, ECU is reading an oxygen sensor signal being inconsistent with other engine sensor's signal, or signal is out of the range yet accepted, an O2 sensor-related trouble code will be triggered ending up in check engine light issue. CEL or MIL or FI errors abbreviate these failures. While check engine light is on, ECU runs in so called lean limp mode. Safe mode restricts both the fuel trim and the ignition timing and develops an overall limitation on performance, until problem diagnosed and resolved definitely. Therefore if you modified your engine with any upgrade causes the oxygen sensor deliver lower signal than normally, you need to wire up an Oxygen Sensor Simulator. Although your ECU will be tweaked, mixture's air fuel ratio still will remain incorrect hence decatting or any other exhaust modification. Simulators help you remedy CEL problems but will not achieve that basic remapping is crucial when decatting or modifying an exhaust. You might be interested in our further performance chips in order to boost engine horsepower, improve fuel efficiency or both at the same time.

get rid of MIL light for good

Shipped super fast fairly well wrapped. Very easy to install. What it will do: it will get rid of MIL light for good and allows you to set richer mix which I am pleased about. MIL warns you when certain limit reached. What is does not do. I though it will change shift points but unnoticeable. Will not increase horsepower or fuel economy beyond the loss due to safe mode. What magnum can do: to keep up awesome tech support. So all the way it is worth the money with minor infirmities. I recommend this product.

excellent service follow up

I have had to contact Magnum Tuning on a few occasions for advice on connecting up my Dyno chip and Oxygen simulator On all occasions they have been extremely helpful and made the job easy I would recommend Magnum Tuning to anyone wanting performance chips

it rectifies MIL

Ordered based off research I've done, hoping to better my gas mileage a bit as it rectifies MIL and prolong the life of the engine not running in safe mode. I assure you, everything OK. Things to note for those thinking about ordering: They ship from stock and shipping was remarkably quick, it is free. The description is adequate; the picture shows the actual item, however, it doesn't show the sim inside. If you need more than one, order the quantity you require with that in mind.

cost effective way to rectify issue

Before I purchased my unheated o2 simulator I should have read other reviews and part description that says OEm sensor must be kept in the exhaust screwed in. Did not blame magnum, absolutely my bad. They still traded in and replaced my simulator. Excellent service and cost effective way to rectify issue with clogged cat converter.
